IMPROVEMENT I IN STUMP-EXTRAGTOR.

'IO ALL WIIGM I'I MAY CONOERN:

Be it known that I, HIRAM LEMM, of Lconidas,'in the county of St.Joseph, and State of Michigan, have invented new and useful improvementsin Machine for Extracting Stumps; and I do herebv declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the ait to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates to certain new and useful improvements on amachine for extracting or drawing stumps from the ground, or forraising,` or lifting heavy bodies, or for any other similar purpose; andthe invention consists in a novel arrangement of the various partsconstituting the machine, and in the construction of the same, wherebymany important advantages are obtained, such as, for instance,simplicity and facility of operation, ease of management, etc., as willble obvious from the following detail description of the same, referencebeing had to the accompanying-plateof drawings, in which- Figure 1 is anelevation of one end of' the machine; and

Figure 2, a vertical section, taken in the plane of the line :c :21,iig. 1.

Similar letters Yof reference indicate like parts.

A A, in the drawings, represent the framework of the machine, which isto be of any suitabie construction to.acconunodate the working partsofthe same; B, the windlass shaft, hung and turning in suitable bearingsof the upper portion'ot` the framework A. This shaft, around itsperiphery, is provided with two ratchet-wheels, C and D, separated by aflange or raised lip, E, and surrounded by a similar raised lip orilange,-F. Withthesc ratchet-wheels pawls Cr engage, two to each wheel,and at points diametrically opposite to each other; the whole series ofpawls being hung to a common rocking cross-bar, H, of the king-posts Iof tbe framework A. One oi' the two pawls for eacn of theseratchet-wheels C, and those upon the same side oi' the said wheels, ismade of a hooleshape at its end, which engages with the said wheels, andthese pawls act to revolve the ratchet-wheels, as the bar II, to whichthey are hung, is rocked in a suitable direction therefor, as will behereinafter explained, while the other pawls serie to hold and preventthe said ratchet-wheels from turning backwards. To the rocking i.cross-bar I-I lever-arms .I are attached, which extend 1n oppositedirections therefrom to each side of the machine,

in the outer ends of which lever-arms J, ropes or chains Ii are hung,that, passing downward, are passed around pulleys L on the sills ot' theframework A. To each end of the wiudlass-shaft chains M are hung, which,when the machine is to be used for extracting stumps, are iirst, in anysuitable mannerpfastened about such stump, and then, power being`applied to the windlass-shaft through the rocking cross-bar, are made towithdraw or extract thc samefrom the ground, as they are thus wound uponthe said windlass-shat't, when the stump, having been suiiicientlyextracted or raised, it is then lifted away from the pit or hole in theground left by it, by attaching or hanging to it a chain, N, passingfrom the windlass-shaft over the pulley O ol the horizontal beam or armI ofthe framework A.

From the above description of my improvement in machines for extractingstumps, it is plain to be seen that it can be accomplished in aycomparativelyT easy manner; that the strain upon the ratchet-wheels isequalized, and the friction on the bearings of the drum lessened,besides many other advantages, which are obvious without any particularmention herein.

I claim es new, and desire to secure by Letters Patentv Theratchet-wheels separated by a ilange, F, of a common windlass-shaft, B,pawls Gr hung to a common rocking cross-bar operated through lever J andchains M, in combination with each other, substantially as and for thepurposes described. v

The combination with the above o'il the cha-in N, passing over beam Pofthe framework A, substantially as und for the purpose specified.

HIRAII LEMM.
